Объяснение:

Х^2-16-(х^2-6х+9)=

=х^2-16-х^2+6х-9=

=6х-25

Answer 3

To simplify the given expression (x + 4)(x - 4) - (x - 3)^2, let's follow these steps:

Step 1: Expand the first two terms using the distributive property (FOIL method):

(x + 4)(x - 4) = x^2 - 4x + 4x - 16 = x^2 - 16

Step 2: Expand the third term:

(x - 3)^2 = (x - 3)(x - 3) = x^2 - 3x - 3x + 9 = x^2 - 6x + 9

Step 3: Subtract the expanded third term from the expanded first two terms:

(x^2 - 16) - (x^2 - 6x + 9) = x^2 - 16 - x^2 + 6x - 9 = 6x - 25

So, the simplified expression is 6x - 25.
